quard link and driving kilrum and has for an object to provide an improved construction wherein the links willbe held against lateral movementas they pass around the driving drum. a

Anotherobject of the invention is to provide a jacquardlink formed with guiding and steadying grooves together with steadying and bracing bar extensions.

A further object of the invention is to provide a jacquardlink in which means are arranged'on the base forpreventing lateral movement of the link while the body is arranged with continuous passage-ways for receiving guiding bars or "rods.

An additional object is to provide a jacquard linkand drum formed so that they will interlock in a certain sense during the passage of the link around the drum, the drum being formed with guiding grooves and bearing surfaces for fitting suitable recesses and projections on the'links to perinit this interlocking action.

by" numerals, 1 indicates an idle drum of' any desired kind and 2 a driving drum of a special construction for receiving the jacquard link chain?) formed of specially constructed links 41 hereinafter fully described.

'The general assemblage as shown in Figure l is the usual assemblage for links: of this kind and as disclosed in my prior Patent No. 1,059,918, issued April 22, 1913. "In this patent the drum is providedwith a groove for receiving projections froin -the link whereby the link is prevented lateral niovenient. When the par'ts ar'e new, lateral movement-is preventedbut as the llnksis used the depending portions wear more or less and consequently a slight movement is I liable to occur and,' consequently,- the action of" the bars or pins fitting in the apertures of the links will not be proper. Y v L i In the 'present'construction it is aimed to overcome these object-ions and provide a steadying bracing structure which will readily wear a sutlicient amount to allow an appreciable lateral movement. In constructing astructure of this kind the respective links at are provided with a frame 5 n erg ing into a body 6, which in a certain sense conforms tothe holes or passageways 7 extending through the frame and body." As indicated in Figure'12, thebody 6 presents "a scalloped outer surface whereby the walls surrounding the passage-ways 7 will be comthe weight of the link reduced while frame 5 affords ample stiffening means. The frame 5 at the lower end merges into a single" lug 8 extending in one direction and a pair of spaced lugs 9 andlO extending in'the oppo' site direction, said lugs forming one linkof thechain 3. The lugs'9 and 10 are spaced apart for receiving between them lug 9 of the adjacent link. The outer edges of lugs 9 and 10 fit rather snugly between the flanges 11 and 12 of the drum 13, and thoughjsaid fit is sufliciently loose to allow a free motion it will not allow any appreciable side movement. As these lugs depend and as the outer bearing lugs 14 and 15 also depend,

grooves 16 and 17 are presented for receivprior. patent above mentioned are maintained and in addition the bearing surfaces of the rounded ends 18 are secured so that it will require a very large amount of wear to cause the link to tilt an undesirable amount. Also, by reason ofth-e body 6 the apertures 7 have a continuous wall fromone side of the link to the other whereby a pin entering any of the apertures will freely pass to the next aperture. If desired, steel brushings 25 could be provided as shown in Figure 5 whereby the link can be made out of vvery light material and yet have ample resistance to wear. The same is true in regard to the bearings for the pin 21, as for instance, auxiliary, steel or other bearing sleeves26 can be arranged in the chain (Fig.

4). Preferably andin fact it is almost,

necessary to make the links out of a light composition and such composition is liable to wear to a great or less extent so that frequent renewals will be necessary to obviate this. Bearing sleeves 25 and 26 may be provided and, consequently, a light structure will be provided and one which will have a longer life. i j

What I claim is 1 t 1. In a link of the class described a pin supporting body provided with a downwardly extending projection on eachside having a rounded bearing surface and a chain link rigidly associated with the lower part of said body and spaced a predetermined distance from each of said downwardly extending projections and forming therebetween a flange engaging groove.

2. In jacquard link mechanism of the character described, a link frame having a body, said frame and body having passageways extending therethrough in parallel. re

lationship, and a link structure extending from one end of said frame.

3. In a jacquard link mechanism of the character described a link body, a link member projecting from the lower end of said body, spaced projections arranged on each side of said link member whereby spaced o-rooves are presented and a driving drum having bearing portions adjacent each side engaging frictionally the lower part of certain of said projections and flanges on the drum extending into said grooves for guiding and holding said body as it passes around the drum. 1

4. In ajacquard link mechanism of the class described a link body, an integral link member projecting from saidbody, a pair of integral projections arranged onthe bottom of said body spaced from said link member, each of said projections having an arc-shaped lower bearing section and a drum having bearing portions engaging said arcshaped bearing portions of the projections and flanges projecting between the projections and the linkmember.

5. In a jacquard mechanism of the class described, a link body, a lateral downwardly extending projection depending on each side of said body,-said projections having are shaped bearing surfaces, a link memberprojecting between, said projections and at a spaced distancefrom each projection, a

drum, a pair of annular flanges spaced from each other arranged on said drum, SELlCl-ELD- nular flanges being adapted to fit in said spaces between said projections and said link. and an annular bearingsurface on said drum adjacent the outer side of said flanges coacting withthe bearing surfaces of said projections. t

6. In a jacquard link mechanism of the character described, a link frame having openings at opposite sides thereof adapted to receive through them a pin and means intermediate said sides for positively directing the pm from one of said openings to the other, and a hnk structure extending from one end of said frame.
